My invention relates to such a construction oi' a bench-vise thatthereby I am enabled to secure a perpendicular movement ofthevise, whichis so made that, by an arrangement of tongues and grooves, itlwill slideup and down between two standards or sideways, it being raised andsecured by means of a lover and pin, or by a set-s crewfplaced under itslower end, and operating upward against it 5V and' j", in the side oi'the standard rf as a i'ulcrum, l and w-orks against another pin ornojection,

g, on the back oi' the sliding inner jaw, b, so that when the long armol' the lever pressed down it raises the sliding jaw o by the short Iarm pressing up against the pin ff, the onteijaw being raised along withit. The pin l1, which passes through the two uprigliis ofthe Standard,Fig. a, is for supporting the jaw I after it has been raised bv theleverj. The

Through the jaws Z) and c are a nun/iber oi" holes, as many as maybedcsired, iorthe 'pur l pose of shifting the position of the piseserewd. By these arrangements I am enabled to raise or lower my vise quicklyI ndeas1ly,and also to use many of my ioolswith greater advantage thanheretofore-as, for instance, the

draw-knife-the trouble in th-iscase having been that the handle eonresincontact with the' surface of the bench. rlVith my' improvement no such-diilieulty exists, -ibr I raise the vise iar'enough above the surfaceof thebench also, by means of slots or holes, the screw of the y toavoid it; also,in planing a board lying upon vise may be shifted up anddown at pleasure. To enable others skilled in the art to make anduse myimprovement, Izwill describe its construction and mode of operation.
